摘要
GPS高程曲面拟合的方法较多,我们利用移动多项式曲面拟合的基本原理,探讨了不同模型对已知点数量的多少以及已知点与拟合点之间的位置关系对精度的影响规律,通过在实际工程中的实验研究,对GPS实际生产作业具有一定的指导意义。
There are a lot of methods to fit curved surface of GPS Height. This paper discussed the impact rule on precision of different model which is caused by the number of points and the relative position of known points and fitting points. It has certain directive significance to GPS production through the experiment research in the actual project.
